WaveSurfer is an audio editor widely used for studies of acoustic phonetics.

It is a simple but fairly powerful program for interactive display of sound pressure waveforms, spectral sections, spectrograms, pitch tracks and transcriptions.

It can read and write a number of transcription file formats used in industrial speech research including TIMIT.

[1] Wavesurfer provides basic audio editing operations, such as excision, copying, pasting, zero-crossing adjustment, and effects such as fading, normalization, echo, inversion, reversal, replacement with silence, and DC-removal, but, in view of its scientific orientation, does not offer effects of interest to musicians such as flange.

It therefore runs on most platforms, including Microsoft Windows, Mac OS X, Linux, Solaris, HP-UX, FreeBSD, and IRIX.
